Why Orlistat's Mechanism Makes It Effective
How Orlistat Blocks Fat Absorption
Orlistat 120mg works through a well-established mechanism that targets lipase enzymes in your digestive system. These enzymes normally break down dietary fat so it can be absorbed into your body. Orlistat inhibits approximately one third of these lipases, meaning roughly one third of the fat you eat cannot be digested or absorbed. This unabsorbed fat passes naturally through your system, reducing your calorie intake from dietary fat.
The Science Behind Fat Blocking
Unlike appetite suppressants that work in the brain, orlistat acts locally in your gut. It's not significantly absorbed into your bloodstream, making it a targeted approach to weight management. When you take orlistat 120mg with a meal containing fat, it binds to lipase enzymes and prevents them from breaking down approximately one third of that dietary fat. The remaining two thirds is still digested normally, which is why maintaining a lower-fat diet is essential for both effectiveness and minimising side effects.
Why This Mechanism Proves Orlistat Works
The fat-blocking action of orlistat provides visible proof it's working. When unabsorbed fat is eliminated from your body, you may notice oily stools or spotting - this demonstrates the medicine is successfully blocking fat absorption. This mechanism-based evidence gives you confidence that orlistat 120mg is actively reducing your calorie intake from dietary fat as part of your weight management programme.
Orlistat vs Xenical - Same Proven Mechanism
Both generic orlistat 120mg and branded Xenical 120mg contain the same active ingredient and work through identical fat-blocking mechanisms. At EverydayMeds, orlistat 120mg costs £32.99 for 4 weeks (£29.69 with EDM10), while Xenical costs £42.99 (£38.69 with EDM10). The mechanism and effectiveness are identical - you're simply choosing between generic and branded options. Alli 60mg uses the same mechanism but at half the dose, blocking a smaller proportion of dietary fat.
Maximising Orlistat's Fat-Blocking Effect
Understanding how orlistat works helps you use it most effectively. Keep meals to approximately 15g of fat each to optimise the mechanism while minimising side effects. Take one 120mg capsule with each main meal containing fat - if a meal has no fat, you can skip that dose since there's nothing for orlistat to block. The fat-blocking effect occurs with each dose, so consistency with meals helps maintain steady weight management support.
